Canyon Crime Scene — Carol Ericson

His sister is missing and only one person can help

Cade Larson needs LAPD fingerprint expert Lori Del Valle to help track down his troubled missing sister. But he can't deny the sparks still between them…nor the secret Lori is keeping. When fingerprints link Cade's sister to another missing woman -- and a potentially nefarious treatment center -- Lori volunteers to go undercover. Will their dangerous plan bring a predator to justice or tragically end their reunion?
